FIELD OF THE INVENTION

The present invention relates to sling attachments, sopmod stocks and,more particularly, to a rotational insert for the sopmod stock.

BACKGROUND OF THE INVENTION

Currently, all sling attachments are non-movable sling mounts. Thisstyle sling mount limits the operator to only one attachment point onhis rifle, thus limiting the shooter's ability to switch from theirstrong side shoulder to their weak side shoulder without slinginterference. In addition, it limits the operator's choice of mountingtheir sling to either the left side of the firearm, the right side ofthe firearm, or in the lower middle of the receiver, directly under thebuffer tube, and directly in line with the shooter's hand.

Also, this style sling mount limits the operator to only one attachmentpoint on their rifle, the left side of the firearm, the right side ofthe firearm, or in the lower middle of the receiver, thus, limiting theshooter's ability to switch from their strong side shoulder to theirweak side shoulder without sling interference.

These mounting locations make it difficult to transition from strongside, to weak side, when shooting from behind a barrier/barricade, whenengaging targets while shooting out of a window of an automobile, orwhen clearing the corners inside of a room.

Moreover, by mounting the sling to the left side of the firearm, theright side of the firearm, or in the lower middle of the receiver,directly under the buffer tube, it places the sling directly in linewith the shooter's hand and could possibly interfere with shooters whohave large hands or if they are wearing gloves.

All of the AR style collapsible stocks that are currently being soldhave built-in sling attachment points that are non-movable and eithermount on the left side or the right side of the stock.

Lewis Machine & Tool Company (LMT) and Bravo Company manufacture twosimilar style stocks. LMT manufactures the SOPMOD/Crane Stock and BravoCompany manufactures a similar design, referred to as the B5 SOPMODstock. This stock design is used, and preferred, by many Special Forcesand SWAT Teams around the world.

The limitations of the prior art are addressed by providing a riflestock for a firearm. The rifle stock comprises a body with a bore havinga forward opening that receives a rifle buffer tube. The body of therifle stock defines a pocket at a level below the bore. The pocket ofthe body has a forward opening, and the stock comprises a sling supportelement. The sling support element has a mating element pivotallyreceived in the pocket.

Tech-10 Tactical found a way to improve on this popular design and makethis style stock even better for the operator. Tech-10 Tacticaldeveloped an insert for the front of the stock that is guaranteed togive every operator a major tactical advantage over any stock currentlyon the market today.

This accessory converts the current SOPMOD stock into a stock where youhave a full 190 degrees of rotation, with a single point sling, whenused in conjunction the Stubby Sling Mount.

This allows the shooter to transition from strong side, to weak side,with no interference from their sling or when shooting from behind abarrier/barricade, engaging targets while shooting out of a car windowor when clearing rooms/corners inside a building.

Finally, by mounting the sling directly at the front of the stock andunder the buffer tube the shooter's hand never comes in contact withtheir sling.

The Swinger Stock & Stubby sling mount consists of two individual piecesworking in concert to produce a user-friendly design while making it themost secure Quick Detachable (QD) style sling mount on the market today.

The first of the two pieces is the Stubby sling mount. It is made of 304stainless steel. The sling mount measures 1.75″×1 ½″×⅜″ and has ¼″ holeson the left and right side of the sling mount, at the top and at thebottom; and in the middle, is a ⅝″ hole designed for a QD insert to beinstalled and held in place using epoxy and ¼″ pins inserted in the leftside and the ride side of the Stubby sling mount.

The Stubby sling mount will rotate a full 180 degrees. Thus, allowingthe user to easily switch from one shoulder to the opposite shoulderwithout any interference from the sling.

Also, by placing the sling mount in the middle of the stock, anddirectly at the front of the stock, it completely eliminates any contactof the sling with the shooters hand while their hand is on the pistolgrip.

However, the most significant advantage of this design, mounting the QDinsert at the front of the stock, is when the weapon is not shoulderedbut it is being suspended in air by the sling.

Since the weight of the weapon is exerting a downward force on thesling, this new design capitalizes on this downward force and uses it topush the QD sling mount upward and into the QD insert. This eliminatesall stresses on the ball bearings located around the base of the QD.

As an example, the very best QD sling mount on the market today requiresabout 450 psi of pressure to pull the QD sling mount out of the QDinsert. With this newly designed stock and sling mount, it is virtuallyimpossible for the QD sling mount to be pulled out of the QD insert.

The weight of the weapon is pushing the QD sling mount into the QDinsert located on the stock. It is not pulling the QD sling mounttangentially or out of the insert, which is how all other QD slingmounts are currently manufactured to remain secured.

This new concept totally eliminates any stresses on the ball bearings,unlike every other QD sling mount on the market.

Also, byplacing the sling mount in the middle of the stock, it completelyeliminates any contact of the sling with the shooter's hand while theirhand is on the pistol grip.

The most significant advantage of this design, mounting the QD insertinto the front the stock, is when the weapon is not in use but it isbeing suspended by the sling as it hangs down in front of the user.

Since the weight of the weapon is exerting a downward force on thesling, this new design capitalizes on this downward force and uses it topush the QD sling mount upward and into the QD insert. This eliminatesall stresses on the ball bearings located around the base of the QD.

As an example, the very best QD swivel on the market today requiresabout 450 psi of pressure to pull the QD mount out of the insert. Withthis newly designed stock, it is virtually impossible for the QD mountto be pulled out of the QD insert.

The weight of the weapon is pushing the QD insert downward on to the QDswivel. It is not pulling on the QD attachment point, which is how allother QD sling mounts are currently manufactured.

The accessory for the LMT and Bravo Company SOPMOD stock utilizes twoindividual pieces, a custom made insert that mounts into the cavity atthe bottom center of the SOPMOD stock, and a 3/16″ tension pin to securethe insert firmly in place so that it will never accidently fall out ofthe stock.

The accessory is designed to be used with the Stubby Sling mount. Afterinserting the Stubby Sling mount into the front of the stock it allows afull 190-degrees of rotation with a single point sling while attached tothe firearm.

The material of the insert is made of glass filled polymer for itsdurability.

By using this accessory with the Bravo SOPMOD stock, it allows yoursling to be mounted on the front the stock and offers 190 degrees ofrotation. With other stocks you have only two options, you can mountyour sling on the left or right side of the firearm and offers norotational advantage. This causes undue sling tension when switchingfrom a strong side to a weak side shooting position.

In addition, when the operator isn't shooting his weapon the firearm ishanging down in front. Tech-10 Tactical saw an additional opportunityand designed the accessory to capitalized on it.

With the weight of the weapon exerting a downward force on the sling,our design capitalizes on this downward force and uses it as anadvantage by push the Stubby sling mount upward and into the QD insert.This design eliminates all stresses on the ball bearings located aroundthe base of the QD and essentially eliminates any chance of theattachment point from pulling out of the insert.

Moreover, the very best QD attachment on the market today fails at about450 psi of pulling force on the insert. With our Stubby sling mount, itis virtually impossible to be pulled out of the QD insert. The weight ofthe weapon is pushing downward on the Stubby Sling Mount, it is notexerting a pulling force at the attachment point, so it cannot be pulledout.

The present invention can be assembled by following these steps:

Step 1: Place the SOPMOD stock, the insert, the 3/16″ roll pin, a smallhammer and the roll pin punch in front of you.

Step 2: Stand the stock up on the butt pad Place the custom made inertinto the cavity at the front of the stock.

Step 3: Place the custom made inert into the cavity at the front of thestock. Next, take your hammer and tap the insert into the cavity untilit comes to a complete stop. If performed correctly you should be ableto see thru the hole without any material being in the way.

Step 4: Insert the 3′16″ roll pin into the hole on the side of thestock.

Step 5: Take the hammer and slightly tap the 3/16″ roll pin until it isflush with the side of the stock.

Step 6: The edge of the roll pin should be even with the stock and theinsert.

Step 7: When the insert is complete it should resemble FIG. 10 and FIG.11.

Step 8: Place the Bravo stock on the buffer tube of your weapon.

Step 9: Insert the Stubby sling mount into the attachment point at thefront of the stock.

Now conduct a function check. Pull on the sling while making sure theStubby Sling Mount remains securely fastened to the SOPMOD stock insert.Once you have verified the sling is securely fastened you are ready touse your firearm.
